The
source for the following is Halsbury’s Ecclesiastical Law 1975
vol 14 para 1166. There do not appear to have been any significant changes
in legislation since that time.

The
incumbent has a duty to look after the parsonage house.
This duty is equivalent to that of a tenant.

If repairs are required then the incumbent must notify the Diocesan Parsonages
Board.

The Board would normally send a surveyor to inspect the property.

The incumbent can carry out the repairs either with general or special
approval of the Board. This would include emergency repairs.

The incumbent cannot make additions
or alterations to the parsonage, or any glebe building, without the consent
of the Parsonages Board and the patron.
If the incumbent acts without consent they can be required to undo what they
have done.
If the Board refuses consent to make changes then they must give notice of
this and the incumbent has a right to make representation to them.

The main legislation appears to
be the Repair
of Benefice Buildings Measure 1972 which can be found in Halsbury’s
Statutes available in most large libraries. The former legislation, the
wonderfully named Ecclesiastical Dilapidations
Measures (from 1923 to 1951)
were repealed almost entirely by the 1972 Measure.

According to Mark Hill the incumbent cannot dispose of the parsonage house
without the approval of the Board and the Church Commissioners. He cites
the Endowments and Glebe Measure 1976 section 15.
